They are certainly the most beautiful saddles, but when I look at pictures like these I see the opposite of what every expert says is good for me in term of long-term health: the center is protruding to pressure soft tissues. It's the main reason why I have yet to plunk down nearly $100 on one.
Another reason is the prolonged break-in. And the fact that you can't get it wet. And you have to baby them with pomade.
And... I already have a Specialized Alias carbon/Ti saddle I like very much.
